Benefits of technology
The design maximizes volumetric efficiency, ensures mechanical reliability, and achieves low ESR characteristics by increasing the surface area per unit volume, thereby enhancing capacitance and reducing manufacturing costs.
Problems solved by technology
Therefore, the condenser element 11 vulnerable to heat is damaged.
As a result, the thermal impact applied to the condenser element 11 breaks dielectric, and thus characteristics of a product is deteriorated and a defective product is produced, resulting in a rise of the manufacturing costs.

Abstract
A solid electrolytic condenser includes a condenser element, an anode wire including one end inserted into the condenser element, a cathode drawing layer formed on outer side of the condenser element, terminal reinforcements arranged respectively under opposite side portions of a bottom surface of the condenser element, a liquid epoxy resin filled in spaces between the terminal reinforcements and between the bottom surface of the condenser element and top surfaces of the terminal reinforcements, a molding part surrounding the condenser element while exposing the other end of the anode wire, an end portion of the cathode drawing layer, and bottom surfaces of the terminal reinforcements, and anode and cathode terminals formed by a plating layer provided on the bottom surfaces of the terminal reinforcements and on opposite side surfaces of the molding part. The liquid epoxy resin includes fillers of a smaller size than those in the molding part.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of Korean Patent Application No. 10-2009-0074300 filed with the Korea Intellectual Property Office on Aug. 12, 2009, the disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1.
